Synthesis and Application of Two Novel Phosphorus bromine Synergy Flame Retardants |
| |
| Abstract: | Two novel brominated phosphate flame retardants tetra(2,3 dibromopropyl)glycol diphosphate and 1,2 bis(5,5' dibromomethyl 1,3,2 trioxyl 2 oxaheane)ethane were synthesized on basis of the materials of glycol,2,3 dibromopropyl alcohol or dibromoneopentyl glycol,phosphorus oxychloride.The structures of both of compounds were characterized by elementary analysis and IR.PUFF was treated with former compound,when the add on was 20%,LOI reached 25,burn rate decreased by 64% compared with original PUFF. |
